设置为我对话的最大宽度 [英] setting a max width for my dialog

问题描述

我的对话框使用的LinearLayout其根源，其使用以下code作为它的自定义主题：

My dialog is using a linearlayout for its root, and its using the following code as its custom theme:

    <style name="HuskyBusDialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowBackground">@drawable/panel_background</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:colorBackgroundCacheHint">@null</item> 
</style>

是否可以设置一个最大宽度？它在手机上，但我尝试优化它的平板电脑好人，他们是太大了。

Is it possible to set a max width? Its fine on phones but im trying to optimize it for tablets and they are too big.

推荐答案

这是老问题，但没有答复是合适的，但你可以在这里找到一些提示：<一href=\"http://stackoverflow.com/questions/6624480/how-to-customize-the-width-and-height-when-show-an-activity-as-a-dialog\">How显示一个活动作为一个对话框时，定制的宽度和高度

An old question, however no replies are suitable, but you can find some hint here: How to customize the width and height when show an Activity as a Dialog

这有助于定制的宽度和高度，而不是设置最大宽度和高度！为了实现这一目标上使用对话的主题活动，我不得不做两件事情：

This helps customize the width and height, but not set the max width and height! To achieve that on an activity using a dialog theme, I had to do a couple of things:

1）设定的布局听者时对话框布局被设置为知道

1) set a layout listener to know when the dialog layout is set.

2）调整对话框布局，如果其大小超出了期望的极限，有效地设置最大尺寸

2) Adjust the dialog layout if its size was beyond the desired limit, effectively setting max size

下面是我目前使用的工作片段，的setContentView（）之后调用：

Here is the working snippet I'm currently using, called after setContentView():

    getWindow().getDecorView().getViewTreeObserver().addOnGlobalLayoutListener(
            new OnGlobalLayoutListener()
    {
        @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
        @SuppressWarnings("deprecation")
        @Override
        public void onGlobalLayout()
        {
            adjustDialog();
        }
    });

现在对话框的大小调整，实际屏幕尺寸的百分比：

Now the dialog size adjustment, as a percentage of actual screen size:

private void adjustDialog()
{
    Window w = getWindow();
    w.setGravity(Gravity.CENTER);

    int current_width = w.getDecorView().getWidth();
    int current_height = w.getDecorView().getHeight();

    WindowManager.LayoutParams lp = w.getAttributes();

    DisplayMetrics dm = getResources().getDisplayMetrics();
    int max_width = (int) (dm.widthPixels * 0.90);
    int max_height = (int) (dm.heightPixels * 0.90);

    if (current_width > max_width)
    {
        lp.width = max_width;
    }
    if (current_height > max_height)
    {
        lp.height = max_height;
    }

    w.setAttributes(lp);
}
